4 reasons why fish cannot eat chocolate
There are several problems with feeding your fish chocolate.
Chocolate has a high-fat content that creates various problems for your fish. Fish may get a digestive disease, become inactive and fat. A fat fish is prone to get other diseases easily.
Lacks essential nutritions:
Chocolate has high sugar and fat content but nutrition for fish’s metabolic activity. Fish needs high protein food that must have very low fat. They need fiber for their digestive health.
Calcium and phosphorus are the most essential nutrients for fish. If they don’t get the necessary nutrients in their regular food they may get sick and die slowly.
Feeding chocolate once or twice usually would not affect your fish but water quality will reduce massively. Chocolate and sugar will dissolve in water. The sugar will feed the yeast and bacteria in your aquarium.
An aquarium should have more nitrifying bacteria so they can process the fish waste and keep the water liveable. But if sugar-consuming microbes become abundant, they will compete with beneficial bacteria that help to keep aquarium water.
The sugar-consuming bacteria will break the sugar into carbon dioxide which will harm the oxygen level of your tank. They also produce alcohol in water which will make tank water highly toxic to fish.
Cocoa can be harmful to some fishes. Fish will act weirdly if cocoa is toxic to them. It may cause fish death or disease within a short period.
What else can fish eat besides fish food?
Run out of fish food? Don’t worry! There are dozens of human foods that fish can consume. Before jumping on the list, always remember, no matter what you are feeding, overfeeding can be dangerous for your fish.
Egg yolk is a very nutritious food for your fish. But it will reduce the water quality faster than other food. A little bit of egg yolk is enough.
There is a thumbs rule to determine the amount of food. Feed them an amount of food that fishes can finish within 2 minutes.
Vegetables are an important part of the aquarium fish diet. You should feed once or twice a week. Vegetables provide good fiber and nutrition to fish.
Most of the vegetables are good for them. Peas, cauliflower, potato, papaya, pumpkin, cucumber, carrot, etc. are good vegetables to feed your fish.
Cut the vegetables into small pieces and boil them before feeding.
Beef livers have high protein content and low-fat content in them. So they are an excellent choice as fish foods. Boil the liver and smash before feeding.
Fish foods use shrimp as fish food as they can contain high amounts of protein. Boiled shrimps can be fed to your fish after cutting them into very small pieces.
Can sugar kill fish?
Sugar can kill your fish. If you pour sugar in your aquarium in high concentration, it will kill the beneficial bacteria and reduce oxygen level and water quality.
Even a small amount of sugar can also increase the growth of sugar consuming harmful microbes. The microbes produce toxic products that will kill your fish.
So, never use sugar in your fish tank and never feed anything that has sugar in it. However, if you made a mistake, it’s fixable most of the time if you change 40-50% water for 3-4 consecutive days.
Fishes can not eat chocolate as it contains high fat and sugar. Fat can make them sick and works like slow poison and sugar can destroy your fish tank’s nitrogen cycling and help produce harmful bacterias. It’s probably among the worst things you can feed your pet fish.
